This book has combined the design and problem solving skills of engineering with medical and biological sciences to improve health care diagnosis and treatment. Position monitoring system of patients will ensure safety by detecting position displacement after falling from toilet, chair or bed. So it would be possible to take instant measures to treat them which may save life. For this system, IR sensors are used as position sensors which send signal to microcontroller and the position of patients are displayed on LCD and make alarm if patient is in unusual position. This position monitoring...
